IF YOU GO

Comedian John Hodgman has been to the end of the world and back again.

Last year he grew a mustache, donned aviators and a tailored suit to assume the persona of a “deranged millionaire.” Hodgman traveled the country, evangelizing his predictions for doomsday and giving advice for how to survive after the apocalypse.

While the world never saw the Blood Wave — a giant wave of blood — or Dog Storm — which is exactly what it sounds like — Hodgman is left with “That is All.”

The final book joins “More Information Than You Require” and “The Areas of My Expertise” in “Complete World Knowledge,” the author’s trilogy of fake trivia. Hodgman also starred in “Ragnarok,” a comedy special in which he awaited the end of the world with his “followers” last December.

Like a hangover after a particularly bad bender, Hodgman was left with a book of nonsense and a persona no longer relevant after 2012, wondering “What the hell do I do now?”

“I unconsciously decided to end that project by ending the world,” he said. “Although our world didn’t end with Ragnarok, that world ended. When I woke up after the apocalypse, I had to figure out how to go on from there.”

Hodgman said he is taking off his aviators — although he’s keeping the mustache — and transitioning into a casual, personal storyteller for his current tour.

“Now, I need to look around and see who I am now,” he said. “I am a 42-year-old man who grew a mustache on a lark and can’t seem to get rid of it, is married with two human children, with a fantastic career I didn’t expect to have.”

Hodgman said his influence is unexpectedly growing thanks to 20-somethings and his popular podcast “Judge John Hodgman,” in which he settles a listener dispute with each show, such as when gift-giving is required and how to properly respond to tornadoes.

“Isn’t it strange that so many young humans are so captivated with the creaky whining of a middle-aged man?” he asked. “The neurosis of a Marc Maron, or the sort of truly vulnerable self-debasement of a Louis CK. Why are young people into this? I thought they liked boy bands.”

Hodgman said he stood out from his peers when he was a teenager, as the kid who turned a spare bedroom into a den, furnished with a television and lounging couches.

“I would sit there with a snifter of orange juice, watch ‘America’s Funniest Bloopers’ and think myself quite the sophisticate,” he said.

Hodgman said this tour is relevant to a young audience because it allows them to hear from someone who has been where they are now, and knows that there is hope.

“It’s about figuring out who you are,” he said. “Just being yourself is very difficult. It requires a lot of hard work and a lot of people don’t want to do it. It’s the catharsis of a lot of comedy.”

Hodgman said he will be joined onstage by Bill Corbett of the RiffTraxx television show Mystery Science Theatre 3000.
